+# LIBERO Spatial Visual Variations
+
+This derived dataset expands `libero_spatial` with six visual conditions per
+source trajectory: the original LIBERO appearance plus five scene-level visual
+palettes. It preserves the original task states, actions, rewards, dones,
+robot state vectors, proprioceptive observations, task language, and BDDL task
+semantics.
+
+Visual conditions:
+
+- `original`: Original - Default LIBERO spatial visual appearance.
+- `nordic-sage`: Nordic Sage - White marble, pale plaster, light wood, sage cabinet, warm showroom light.
+- `midnight-fjord`: Midnight Fjord - Dark floor, deep blue wall, gray table, navy cabinet, cool low-key light.
+- `terracotta-pop`: Terracotta Pop - Brown ceramic, yellow linen, wood table, clay cabinet, warm terracotta light.
+- `alpine-oak`: Alpine Oak - Wood planks, white wall, light wood table, white-oak cabinet, clear daylight.
+- `graphite-gallery`: Graphite Gallery - Gray ceramic, dark plaster, gray table, charcoal cabinet, crisp spotlight.
+
+The dataset contains ten LIBERO spatial tasks. Each task file contains the
+first ten source demonstrations rendered under all six visual conditions, for
+60 trajectories per task and 600 trajectories total.
+
+Each episode stores explicit metadata:
+
+- `task_name`, `task_index`, `language_instruction`
+- `source_demo_key`, `source_demo_index`, `source_task_file`
+- `visual_condition_key`, `visual_condition_name`, `background_style`
+- `camera_calibration` group with per-camera intrinsics, per-frame extrinsics,
+  and per-frame world-to-pixel projection matrices
+
+Camera calibration is stored at:
+
+```text
+data/demo_*/camera_calibration/<camera_name>/intrinsic_matrix
+data/demo_*/camera_calibration/<camera_name>/extrinsic_matrices
+data/demo_*/camera_calibration/<camera_name>/world_to_pixel_matrices
